烤烟苯丙氨酸类致香物质与土壤理化性状的典型相关分析

Canonical Correlation Between Aroma Aminophenol Contents in Flue-cured Tobacco Leaves and Soil Physicochemical Properties

通过分析河南省12个烟区土壤与烟叶各335个样品的测试数据，采用典型相关分析方法研究了烤烟苯丙氨酸类致香物质含量与土壤理化性状之间的关系。结果表明：苯甲醛、苯乙醇与土壤速效钾含量、粒径0．05～0．001mm的土壤颗粒含量呈正相关，与pH、镁、钙、铁、铝、钠含量呈负相关；苯甲醇与速效钾含量呈负相关，与钠含量呈正相关；苯乙醛与土壤理化性状的各项指标无显著相关性。

335 soil samples from 0-20 cm depths and their corresponding flue-cured tobacco samples from 8 to 12 leaf position were collected from 12 regions in Henan Province in 2008, and then canonical correlation analyses were conducted on the relations between aroma constituent contents of aroma aminophenol in flue-cured tobacco leaves and soil physiochemical properties. Results showed that benzaldehyde, phenethyl alcohol and soil available potassium, soil particle ratio between 0. 05 mm and 0. 00l mm were positively correlated, benzaldehyde, phenethyl alcohol and pH, Mg, Ca, Fe, Al, Na were negatively correlated, benzyl alcohol and sodium were positively correlated, benzyl alcohol and soil available potassium were negatively correlated, but no significant correlation existed between phenylacetaldehyde and soil physicochemcal properties.
